Sorry for the late afternoon digest. We are in the midst of trying to get our lab back up and running! There are several interesting papers today, including a commentary on the holobiont model and the usefulness of integrating microbiome and GWAS data, the development of a “Microbiome-Derived Metabolism Screen” for personalized medicine published in Cell, and a paper investigating phylosymbiosis in the skin microbiome of fish. My non-microbiology pick is a urine sampling method to assess diet, which could be very useful to gut microbiome scientists.

You will find a study investigating the effect of high-fat diet in Drosophila found a microbiota-dependent activation of stem-cells; electronic cigarettes were found to negatively influence the oral microbiome, and glycan epitopes present on enveloped viruses (as COVID-19) can be targeted and neutralized by human antibodies against these foreign glycan structures.
Finally, a helpful article during Corona-times, when more and more courses and meetings are held online, features the use of FAIR training material: Ten simple rules for making training materials FAIR. Enjoy!

We’ve got a decently sized digest today with a lot of environmental microbe papers, including descriptions of novel species. There is also the Cell paper (highlighted) from Peter Turnbaugh’s group on ketogenic diets and the gut microbiome, which has been getting a lot of press. For new bioinformatic and other techniques, we have a new R package to predict functional profiles in Tax4Fun2, an assessment of phylogenetic rooting methods for bacteria, and a description of fiber intervention used in undergraduate classes for active learning.

 Have a great weekend!

Good afternoon from sunny South Wales!

Today’s digest has a lot of great papers, with something for just about everyone. We’ll start off with a bang, and highlight a great paper in which Rajasekaran and collegaues challenge the current dogma that human intervertebral discs are sterile using a 16S rRNA sequencing approach.

We then have an interesting, or perhaps concerning paper looking at the prevalence of underreported parasites in laboratory zebrafish populations. A must read for anybody using zebrafish models. We also have plenty of papers concerning plant and water microbiomes, including a rather huge report on ocean systems.

Finally, with the current health climate, what better paper peruse than the contribution of Qureshi et al. who have demonstrated that gender neutral bathrooms are more rapidly colonised than single gender bathrooms. If recent anecdotal news articles are to be believed (although they seldom are) it’s usually the men letting the side down. You’ve got to wash those hands!

I hope everyone is staying safe, and enjoys today’s post!

Hello from the Sonoran Desert! It is a sunny Sunday over Tucson, Az! I find that Sundays are the best to explore new ideas and concepts, and I especially love to take the time to read a good opinion piece or parse few review papers. In today’s digest, you’ll find a fascinating review on the Tara Ocean expedition and how it changed our understanding of marine microbial communities. If you’re more interested in the human-associated microbiome, fear not! There is also great pieces on the gut microbiota in athletes and on the interaction of oral and lung microbiome in the context of lung diseases.

If like me, you are a computational biologist thinking about microbiome data all day, you should enjoy reading today’s non microbiology pick, a great perspective paper discussing the FAIR (Findable, Accessible, Interoperable and Reusable) data principle and what are the current hurdles that limit open data reuse.

Have a great Sunday!
